Games including The Vanishing of Ethan Carter, Killing Floor, Shadow Complex Remastered, and The Culling are going cheap in the Humble Unreal Engine Bundle. It's a curious thematic grouping but hey, after curating 200-odd bundles you'd be reaching too. Here's a suggestion, Humble: the Humble Unreal Engine Versus Quake Engine Bundle. Let's dust off our best pointless arguments from 1999.
As ever, this pay-what-you-want Humble Bundle is split into tiers, giving more and more games as you pay more.
For at least $1 (£0.80), you'll get smashing co-op wave survival first-person shooter Killing Floor plus a few of its DLC packs, the wonky smash 'em up Dangerous Golf, and the castletroid Shadow Complex Remastered. All of those come as Steam keys for Windows, with varying support for Mac and Linux too.
Shadow Complex Remastered was once free but only through Epic's own client and you've missed that anyway.
Pay more than the average ($4.08/£3.29 as I write this), you'll also get great and gorgeous explore-o-adventure game The Vanishing of Ethan Carter, the stupidly-named and Alec-nauseating VR astronaut 'em up Adr1ft, and toy shooter The Mean Greens - Plastic Warfare. Again, Steam keys. Again, mostly for Windows.
Lastly, pay at least $10 (£8) to get multiplayer Battle Royale 'em up The Culling too. Here's what happened when we sent Brendan into the arena. Also a Steam key, for Windows and Linux.
This bundle will be available for the next fortnight.
I'm quite digging the idea of an Unreal vs. Quake Engine bundle, for old times' sake. Let's say the cut-off points are Quake II and Unreal Tournament, and obviously no Unreals or Quakes are allowed. On the Quake engine side, maybe Kingpin, Sin, Hexen II, Thirty Flights of Loving, and Anachronox. With Unreal, you've got Deus Ex, Clive Barker's Undying, and... X-COM: Enforcer? Perhaps higher price tiers could reach into newer games built on newer versions of each engine.
The point is, Quake II has the best-feeling movement of any first-person game, OKAY?
